[Retracted] Cigarette Smoke Regulates the Expression of EYA4 via Alternation of DNA Methylation Status
Figure 3
EYA4 methylation level in nonsmoker and smoker samples. (a) Lollipop diagram displays the methylation level of 4 CpG islands that located on the EYA4 promoter in DNA extracted from nonsmokers (). White lollipop indicates unmethylated cytosine, black lollipop indicates methylated cytosine, and there was no methylation observed. (b) Lollipop diagram displays the methylation level of 4 CpG islands that located on the EYA4 promoter in DNA extracted from nonsmokers (). White lollipop indicates unmethylated cytosine, black lollipop indicates methylated cytosine, and methylated cytosine was detected in 26% of tested samples. (c) Box blot shows the number of methylated cytosine in nonsmoker and smoker adults. , two samples -test.
